An operating system kernel minimizes the frequency of disk access by keeping a pool of internal data buffers which helps to increase the response time, this is known as?
Correct Answer: A
Question 931 Explanation:
The buffer cache (in an operating system, but also in a DBMS) is main memory (i.e. RAM) used as a cache to reduce the number of physical read/writes from mass-storage devices (like hard disks, for example), since these operations are slower by several orders of magnitude compared to the same operations done on main memory.
